DE1133936B - Vegetative propagation of mother plants of a floribunda rose - Google Patents

Description

The invention relates to the continuous, occurring over any multiplication stages up to the sale item vegetative propagation of mother plants of a rose, especially as a cut rose shows greatly increased shelf life in the vase, belongs to the species Floribunda and half-filled geranium red, has flowers that merge into vermilion, long stems and dense foliage. Such a variety, especially in this color scheme, is absolutely new in the class of floribunda roses.

In the horticultural industry, several rose varieties of the Floribunda species are known, their Flowers are geranium-red, e.g. B. SIREN, KORDES SPECIAL MESSAGE and MOULIN ROUGE named varieties. However, these roses usually have the following defects:

1. The roses mentioned do not show any durability of the cut ones beyond the normal extent Roses in the vase.

2. When using the plants in gardens: the stems are weak; the flowers are too strong filled and are not very durable in rainy weather; the petals change color blue when fully in bloom and the foliage is insufficiently dense.

3. When used in the greenhouse: shape and durability of the flowers leave something to be desired left over, and the ability to flower is too low.

To create the new rose, the inventor proceeded as follows: The inventor led, as usual, Thousands of crosses through artificial insemination.

In order to create a product exhibiting the above-mentioned characteristics, plants of two Thousands of varieties of roses crossed. The variety MOULIN ROUGE was used as the mother rose (seed carrier) chosen. The variety known under the name FASHION was used as the father rose.

As a result of this controlled fertilization, numerous fruits emerged, the seeds of which were removed became. The seeds of these fruits are biologically different from those from would have emerged from natural self-fertilization, for they arose as a result of fusion from two cells derived from two different parent plants.

The above-mentioned seeds were sown, whereupon the inventor received 190 little plants that are differentiated by their Design features and biological characteristics are differentiated from one another. None of these plants pointed Vegetative propagation of mother plants of a floribunda rose

the characteristics you are looking for. The inventor had to root out those plants that did not meet the conditions corresponded to the problem he was trying to solve. From now on, the features and Properties of the retained plants examined. This selection again led to a series of excretions, whereby after extermination of 181 plants only nine were retained.

As with roses in general, there was almost in these retained plants each leaf axilla has an eye that is characterized by its particular vigor, d. i.e., it developed extremely vigorous on a root system called the graft.

In order to fully develop the characteristics found in these plants and to ensure their persistence To secure these characteristics, the inventor removed eyes from each plant, which he placed on suitable supports grafted on. A few months later it resulted in perfectly viable rose plants abundant roots and very well developed foliage.

In the following years carried out the systematic investigations, which concern itself with the plants

existing characteristics, gradually to the elimination of all grafted varieties with the exception a single one that met the conditions set.

The rose had strong branches; the flowers were well formed, opened well in any weather, were very durable, and their petals did not turn blue when they opened. In addition, wai its foliage thick and it was very willing to flower, which makes it look like in the garden and greenhouse raised cut flower was particularly suitable.

Above all, the cut roses showed the desired new property of great durability of the rose in the Vase. It turned out that the new rose was at least 9 days, but usually even more than 14 days remains unchanged in the vase. The new rose was absolutely new to the floribunda class, primarily because of their color; then because of their twisted shape, while other floribunda roses are simple; also because of their long stems. These properties make the new rose special useful for the cut flower business.

Now it was time to see if the new rose was in terms of its uses the horticultural industry would be interested in. In the greenhouse and in the field there were quite a few carried out of experiments to determine the productivity and behavior of plants under different climatic conditions and in different seasons. The results of these experiments were positive and confirmed the importance of this new rose for the horticultural industry in particular as a cut flower cultivated outdoors and in the greenhouse, but also as a potted plant and as a Ornamental plant for plants and gardens.

The characteristics and properties of this new rose grown as above can be are consistently passed on in an asexual way, also referred to as genderless, whereby the preservation of this rose is guaranteed indefinitely. Suffice it to use one eye that both on the industrial plants and on the flower stalks, which will later be available in stores will be found. This eye is grafted onto a surface in any desired way in order to create a plant that is completely identical to the new rose. You can do this also achieve that the propagation by using cuttings of plant tissue parts derived from the rose plant, its botanical and descriptive characteristics are listed below:

In particular, the new rose shows the following main characteristics:

Shape features: The plant, which is French green when the wood is mature, has grown upright, very branched, the flowers are semi-double, geranium-red and merging into vermilion when they open in the open air dark purple pigmentation, solid round petals with a white base spot, the circular edge of which is fuchsin red and the one at the point of attachment to the fruit base is pale yellow is; twisted shape; long, sturdy stems.

Biological characteristics: The rose is very capable of flowering, has a vigorous growth and is against cryptogamic Very resistant to diseases.

The most striking feature of the new rose is that the cut flowers are roughly in the vase Days remain unchanged.
